OMOD files can be opened with OBMM and exported into so-called OMOD-ready ZIP files, which can then be installed manually or by another manager of choice, provided it understands the underlying folder structure, which thanks to scripted installs can be whatever the author had in mind and make totally no sense. 'Most' mods can likely be installed fine by whatever manager you choose, especially simply structured ones, where it's only an excerpt from a Data folder with no options or choices inside. That's just the result of these mods having been released long before mod managers were even an idea, and things like a standardized folder structure were not yet heard of. You will run into mod packaged in a way 'no' manager on earth will be able to correctly install, or others only certain managers will be able to understand, while others won't. I'm not yet using it myself though, so I can't say if it's true. omod format and/or a BAIN folder structure.

I heard rumors Vortex may even understand the.

In Vortex, and previously NMM, you had FOMOD (originally from the Fallout modding scene) install directives, which again resulted in a step-by-step make-your-choices install wizard, or even with C# scripts. They're named/numbered in a way so you can pick&choose, and BAIN will install the combined outcome of your choices. The mod packages are split into many optional, and overwriting, pieces, and each one of these is just a manual install pack, put 1:1 into the Data folder. Wrye Bash's BAIN is more like 'automated manual install'. OBMM is fine for automated guided installs, its wizard-like scripted installs (.omod) being key to many more complicated sessions otherwise. What choice of mod manager, or manual, you use is totally up to you.
